Android，获取屏幕的宽度和高度吗？

Question

I am trying to get the width and height of the screen in Android, i have:

DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
stageWidth = displaymetrics.widthPixels;
stageHeight = displaymetrics.heightPixels;

The width is 1280 but its coming back with 752.

Any ideas?

Answer 1

Try this instead:

Display display = getWindowManager().getDefaultDisplay(); 
stageWidth = display.getWidth();
stageHeight = display.getHeigth();

Is that the same width? Are you sure the width is 1280 and not 752? What device are you testing it on and what height are you getting?

Answer 2

Rotate your screen and see.I think you will get your correct screen size.

The above code worked with me and should work with you.

在展示对象上使用此方法（来自docs）：

void getSize(Point outSize) - Returns the raw size of the display, in pixels.
